A CORPORATION OF PENNSYLVANIA BLOWER Application filed September 14, 1927. Serial No. 219,471.

My invention relates to vertical blowers,

or compressors, of the propeller type, and it has for-an objectto improve the construction of apparatus of this character.

Inapparatus of the class described, the

driving motor and the propeller are usually supported from below by suitable foundation work, upon which the casing may also rest, lVith such an arrangement, considerably headroom is required to permit removal of the casing, inorder to gainaccess tothe motor. 1 i V Furthermore, guide vanes are usually located between the motor and the propeller so that before access can be had to the motor, theepropeller must be removed from above, after which the casing may be raised the desired amount to permit removal of the motor. This procedure is objectionable because of the time and labor required and, in addition, blowing apparatus is often installed inpositions which are inaccessible by cranes. and the like, which would facilitate assembling and dismantling.

Moreparticularly,therefore, an object of my invention is to provide a blower, of the t e described, whichshall be so constructed as to permit the motor and the propeller to be removed as a unit, and. in which this opera nniay be performed without disturbiin; the casing. p 7

Apparatus embodying the features of my invention is shown in the accompanying drawings, in which:

Fig.1 is a sectional elevation of a blower, showing a sectionfth'rough the casing on the lineI-Iof Fig. 2; and,

c Fig. 2 is a section on the line IIII of 1. V V T According to my invention the entire blower is supported from above, and the guide vanes are located abovethe propeller, so that the motor and the propeller may be removed as a unit. Preferably, the motor, andthe propeller are suspended within the casing by means of suitable supporting members which also serve to reinforce the casmg.

Referring now to the drawings for a better understanding of myinvention, I show a vertical. blower, indicated generally at 10, and

comprising a converging-diverging casing 11, in which a propeller 12 1s d1sposed. A suitable motor, such as a turbine, or an electric motor 18, is disposed below the propeller and connected for operating the latter. I

Extending longitudinally of the casing 11, and secured to the exterior thereof, are a number of channels 14, which are adapted by any suitable means, such as the gusset plates 15, to be secured at their upper ends to a supporting structure, as to the deck of a ship, and at their lower, or depending ends to carry a suitable framework 16, for supporting the motor and the propeller.

The framework 16 preferably takes the form of a suitable number of channels, or the like, 17, which extend transversely of the casing and are arranged to support the motor I in any suitable manner, the channels 16 being 7 as the flange 20, is provided on the motor casing, audthis flange is adapted to rest on the channels 17, and thus, to transmit the weight of the motor and of the rotor elements of the blower to the channels 17. These channels 17 are secured at their outer ends to the lower, or depending; ends of the channels 14. In order to do away with the necessity of removing the propeller and motor as separate units, I dispose the guide vanes 21 and bearing 22 above the propeller and thus, by means of my supporting structure, I am able to remove the propeller and'the motor as a unit by merely disconnecting the framework 16. Also, since the casing only supports its own weight and that of the guide vanes, it may be'made' of relatively light sheet metal. The channels 14 also serve as stiffening members for a casing of this light material and hence,

but also free from any noise whichmight otherwise be produced by vibrations.

It will thus be seen that I have provided a simple, and yet rugged construction which provides for the proper alignment between the casing and the motor elements, and which in aconverQ'ent-diver ent casin a propeller within the casing, and a motor for operatingthe propeller, 'ot a plurality oflong tudinally extending members bent to conform substantially to the contour of the casing and 1 secured thereto, and means for supporting the motor and the propeller from the depending portions oi": said longitudinally extending members.

. 2. A vertical blower coin-prising a casing,

a propeller within the casing, a-motor for driving the propeller, a plurality of members arranged outside of the casing and extending thereof, said casing being secured to said members along co-extensive portions of said casing and said members, means for supporting the motor from the lower porlongitudinall tions ofsaid members, and means for attach ingthe upper portions or said members to a ly-extending members, means for preventing said transversely-extending channels from spreading, and abutment means on said motor and adapted to rest on said channels for supporting said motor.

5. In vertical blower apparatus, the'combination of a vertically-extending casing, a propellerdisposed within the casing for efiecting aiorced circulation of air therethrough, a motor disposed below andfconnected to the propeller for driving the same, a bearing structure disposedabove the propeller and secured to the casing for retaining the upper end portion of the connected motor and propeller in axial alignment with the casing,

structural members extending longitudinally of thecasing and provided'in the vicinity of tlieupper end of the casing with attachment means, and means disposed below and extendin g transversely of the cas ng and connecting with the lower portions of the longitudinally extending structural members for supporting the propeller and the motorrelative to the said supporting means being so arcasin b7 i ranged as to provide iorthe withdrawal of the motor and the propeller, as a unit, axially and downwardly from thecasing.

In testimony whereof, Ihave hereunto subscribed my name this 25th day of August,
